There are thirty-six common Formation Arrays in the Heavenly Realm.

Of course, based on these thirty-six Formation Arrays, other Arrays can also be derived, but this depends on the personal mastery of the Array Master.

Moreover, the same Array, when set up by different people, will definitely have different effects. For instance, the "Nine Palaces Lock Heaven Array," if arranged by Leonidas King, wouldn’t be too effective, but if arranged by a Divine King, it would be a super Big Array.

To create an Array, first you need to be able to refine Array flags, because Array flags are the foundation of an Array. Exotic treasures are secondary; good exotic treasures can strengthen an Array, while ordinary ones can also form the Array.

After entering the mountains, Yusuf Zuck found a cave to burrow into and then spent a day choosing three Arrays out of the thirty-six.

One is the Nine Palaces Bagua Array, which serves as the outer Big Array. The second is the "Heaven and Earth Upside Down Array," the second layer, and the core is the "Five Elements Extermination Array."

He didn’t learn others, focusing only on these three Arrays, meticulously studying and deeply comprehending.

Formation Arrays are much more complex than Alchemy. Yusuf Zuck had insights into Alchemy and possessed Strange Fire, so making Elixirs was not difficult for him, but after he started researching Arrays, he felt the difficulty.

This is because Arrays require calculation, precision, and a macroscopic layout; every detail, every step, every position, etc., must not have any mistakes.

Moreover, not everyone can refine Array flags, and there are even hundreds of types of Array flags. What properties each Array flag has, how much energy needs to be infused, etc., all require conversion.

In fact, an Array is a vast mathematical formula, and unfortunately, mathematics was Yusuf Zuck’s biggest headache during his school days.
